(ABS Hold Pressure Control Function - GF42.30-P-3200GG)
MODEL 463.### ## up to 127356 up to 31.8.01 with CODE (B02) ABS brake system
ABS hold pressure control mode
(ABS shown in models 463.308/330/331 with 2/2-way valves)
If one or more wheels tends to lock during the braking process, ABS prevents a further pressure build-up. The ABS control module introduces the hold pressure phase from the wheel speeds and slip values.
The hold pressure phase is introduced by actuating (closing) the solenoid valves (y6, y8, y20). All the solenoid valves (y6 to y21) are closed in this control phase, with the result that the pressure in the brake calipers remains constant.
